Japan's exports posted the biggest monthly drop in about four years in July, government data showed on Wednesday, as the impact of U.S. tariffs intensified, raising concerns about the outlook for the export-reliant economy.

Japan’s exports sustained their steepest drop in more than four years as US tariffs continued to weigh on global commerce, clouding the outlook for economic growth at a time when personal spending remains unsteady.

Exports fell 2.6% in value from a year earlier, sliding more than the median forecast of a 2.1% decline, the Finance Ministry has reported.
